No. 816,335. Specification of Letters Patent. Patented March 27, 1906.

Application led April 25, 1905. Serial No. 257,299.

ported thereupon a smaller plane 2, the stock 3 of which is held in place by a forward dog 4 and a rear dog 5. As will be seen, the dog 5 is adapted to pass into the opening A in the bottom of the handle 6 and catch upon a projection 7, which-in this instance is a portion of the bottom S of the stock 3. An opening 9 is formed in the bottom 8 of the stock 3, which alines with an opening 10 in the bottom 11 of the .shoe 1, and, as is obvious, the said two openings are for'the purpose of permitting an entrance of the bit of the plane 2. The back end of the opening 1() is tapered, as at 12,for a purpose to be hereinafter explained.

To all. 107mmI it may; concern:

Be it known that I, ALEXANDER KALLA, a resident of New York city, Manhattan bo`rough, county and State of New York, have invented certain new and useful improvements in Carpenters Planes, of which the following is a specification.

One of the objects of the invention is to provide a combination plane with improved means for adjusting the cutting-tool.

A further object is to provide improved means whereby a plane-stock or smoothingplane, for instance, can be attached to a relatively larger stock or shoe, whereby a jackplane is produced, and to permit of said plane-stock or smoothing-plane to be utilized independently of said larger stock or shoe.

- T o these and other ends, which will hereinafter' appear, my invention comprises the novel features of improvement and combination and arrangement of parts hereinafter set forth, and finally pointed outin the appended claims.

Reference is to be had to the accompanying drawings, forming part of this specification, wherein- Figure 1 illustrates my improved plane in plan view, qne end being broken away. ig. 2 is a longitudinal section thereof, the section being taken' on a line a ay in Fig. 1. Fig. 3 is a cross section thereof, the section being taken on a line b b in Fig. 2 and looking in the direction of the arrow. Fig. 4 is a fragmentary sectional plan view, the section being taken on a linee c in Fig. 2. Fig. 5 is a cross-sectional view of the bit-iron, the section being taken on a line d d in Fig. 1, showing the bit,.the clamp for holding said bit, the shave-iron, and means for holding the bit and shave-iron together. Fig. 6 is a fragmentary face View of the bit-iron,V showing the means for adjusting the bit longitudinally, the bit being removed, showing also a portion of the shave-iron, and means for adjusting same. Fig. 7 is a cross-section ofthe clamp-iron, the section being taken on a line -e e in Fig. 1. Fig. 8 is a detail plan view of the cam for clamping the plane-stock and shoe together. Fig. 9 is an end view thereof and shows the angular slot therein, and Fig. 1() is a perspective view of the bit-iron.

Like characters of reference indicate corresponding parts in the several views.

Referring to the accompanying drawings, special reference being made to Fig. 2, the numeral 1 indicates a vshoe which has supmounted thereupon, and to permit of avertical movement, at the same 'time precluding displacement, I mount upon the sides 14 of the plane guides 15, Fig. 4, and upon the bitiron 13' slides 16. As will be seen, the arrangement of said guides and slides is adapted to prevent any tendency toward -movement excepting in a vertical plane. Upon the bottom of the bit-iron 13 I secure a plate 17, which is held against said bottom by screwbolts 18 18, Fig. 3. Said plate 17 is carried beyond the sides 14 of the shoe to an extent which permits the said plate to contact the guides 15. This has for an object to line up the bit of the plane 2 with the bottom of said planewhen detached and used independently of the shoe, as without such provision the bitiron could be raised to any extent and alinement of the bit would be difficult.

Upon the bottom 8 of the plane 2 I mount a segment 19. Within the periphery of the rounded portion of said segment is cut a groove 19a, said groove being angularly disposed with reference to .the axis of the pin 20. (See Figs. 8 and 9.) Within said groove a tongue 2li-upon the plate 17 is adapted to fit. The bottom surface of the nose-21 of the bitiron 13 is designed to come flush with the bottom of the bottom ortion 11 of the shoe 1 when said shoe and) plane 2 are locked toether for use, the rear edge of said nose being slightly tapered to correspond with the tapered edge 12 of the bottom 11 of the shoe 1. The locking process When the plane 2 is detached from the shoe 1, the bit-iron 13 will of course be raised to its highest position, that being when the plate 17 is 1n contact with the guides 15. To raise and retain the bit-iron in this position, it is the arrow, Fig. 3, or, in other Words, to oper- The bit-iron 13 of the plane 2 is movably will now be explained.`

but necessary to operatethe segment 19, as per IIO ' A in the ate it so that the angular groove 19arforces the' plate 17 upwardly and jams it in` place against the guides 15, which act as an abutment. Supposing it to be in this position and I Wish to place the plane upon and lock it to the shoe 1, I place itupon the dogs, as shown by dotted lines B, Fig. 2, the opening bottom of the handle 6 being'large enough to do this. Having done this, the nose 2 1 ofthe bit-iron 13 will be substantially over the opening 10 in the bottom 11 of the shoe 1. By reversing the segment 19 or pushing it opposite to the direction ofthe arrow in Fig. 3 the whole bit-iron will' be forced downwardly, sliding in the guides 15. Thetapered rear ed e of the nose 21 will contact the tapered e ge 12, and further movement will tend to jam the plane 2 against the dogs. It will of course be understood that the, tapered edges referred'to will be designed to Vallow the bottom ofthe nose 21 to aline with the bottom 11 of the shoe 1 substantially at the same time that the said jamming of the plane 2 occurs.

Upon the bit-iron 13 I mount ythe usual bit. 22, special means for adjustment being emloyed. Within the bit 22 I place a lon ituginal slot 23, which may be as long as esirable, and within this slot a block 24,Figs. 2 and 6, is fitted, said block having a projection 25, Figs. 2 and 3, which passes through a transverse slot 26 in the bit-iron 13, Fig. 3, said projection being adapted to work therein. A threaded spindle 27 is rotatably mounted u on saidbit-iron and passes through a t eaded hole Within the rojection 25 of the block 24, a thumb-whee 28 being rovided for operation. The function of the lock 24 is obv1ous*namely, to adjust the bit 22 transversely of the bit-iron 13, or, in other Words, to enable the operator to bring the cuttin edge of the bit in proper relationship Witht ework. When properly adjusted, the bit 22 isheld in place or secured against movement by theclamp 29, Fig. 5, said clamp .being provided with a cam 30, which coacts with an opposite cam 31, which is carried by 'a pin 32, rotatably supported by said clamp 29, a lever 33, Fig. 1, carried by said pin 32, being the means for operation. The clamp 29 is loosely mounted upon the bit-iron 13 and may be movedoutwardl thereby bringing the cams away from the it in the event of a desire to, disassemble. Upon said bit 22AI mount the usual shave-iron 34, Figs. 1 and 2, with s ecial means for adjustment, said means a wheel 35, carried by the bit,-

ein iron 13 saiwheel being provided with teeth 36 upon a ortion of its periphery, a worm 37, carried Ey a rotatable shaft 38, supported upon the bit-iron 13, being the means for rotating the wheel 35, a thumblwheel 39 being provided for the purpose of rotating the shaft 38.` Within the wheel 3.5 I provide an eccentric slot 40, into which a projection 41 of a block 42 42 Works 1n an opening 43, Fig. 6, in the bitiron 13, said opening being provided with guides 44 and said block 42 wlth guideways 45, Fig. 2. The block 42 carries a nib 46, Fig. 1, which enters an opening to :lit it in the shave-iron 34. j By rotatin the wheel 35 by the means described the lock 42 can be moved up or down in the opening 43, thereby moving the shave-iron toward or away from the work. To clamp the shave-iron in position, a clamp composed of a cam 46, carried by said shave-iron, Figs. 2 and 5, and a cam 47, carried by a lever 48, is provided. The lever 48 carries a rotatable spindle 49, which is provided with a block 50, which is within a recess 51 in the bit-iron 13 and under the bit 22. When the lever 48 is rotated properly, the cams 46 and 47 by means of the spindle 49 force the bit and bit-iron together, thereby clam ing same, the bit being held, as has been expljained, by the clamp 29.

To prevent chattering, I provide a clampiron or wedge 52, Figs. 1 and 2, said clampiron bein provided with a hook 53, which is movabIy mounted therein, the means for operation beinga swivel-cam 54, Fig. 7. The points 55 of sald cam 54 will rest Within a recess 56, formed within the iron 52, when the members are not clamped, and when it is desired to clamp the members together the said points 55 will ride up the inctlined sides of said recess l56 when the cam is rotated. This will draw the nose 57, Fig. 2, of the hook 53 up against the bit-iron 13 thereby clamping the shave-iron and bit as a whole against the bit-iron. A spring 58 is provided and is so adjusted as to tend to constantl force the hook 53 backward, this being for tlie purpose of facilitating the disassemblao'e of the clampiron from the bit-iron. At t e back end of the clamp-iron 5 2 a pin 59 is provided to limit the downwardl movement of the back end of said iron, suitable openings being provided in the bit and shave-iron for the hook to ass through, as shown.

Ft will be obvious from the foregoing that the plane 2 can be disengaged from the shoe 1 and used as a smoothing-plane, and. it will also be evident that many of the minor details of construction may be varied without departing from the s irit of my invention.

i `aving now descri ed my invention, what I claim, and desire to secure by Letters Fatent, is-
